Honors Geometry Chapter 3 - Proofs Involving Parallel and Perpendicular Lines

Solve for x

• 4

• 5

• 6

• 7

• 172/37

Which equation would you use to solve for x ?

• 9x + 13 + 85 = 180

• 9x + 13 - 85 = 180

• 180 - 9x +13 = 85

• 9x + 13 = 85

Which rule applies to the the figure?

• When lines are parallel, alternate exterior angles are congruent

• When lines are parallel, consecutive angles are congruent

• When lines are parallel, corresponding angles are congruent

• When lines are parallel, vertical angles are congruent
